What is the pOH of pure water at 60C?
pH = -log(concentration of H+ ion) which indicates acid pOH = -log(concentration of OH- ion) which indicates base In pure water at 25 degree Celsius, concentration of H+ and OH- is equal i.e. 10^-7 mol/dm^3 so, the sum of pH and pOH is -log(10^-7) + -log(10^-7) = 7 + 7 = 14
When you burn a log in the fireplace why is there a difference in mass?
The chemical composition of a log (and most organic substances) is carbon. Carbon when burned becomes oxides of carbon which are usually gases i.e. carbon dioxide and carbon monoxide. Therefore in essence, most of your log is being vaporized. If you were to burn the log in an enclosure such that none of the gases were lost, you would observe no mass difference.
What are observable changes with burning a log?
When a log is burned, observable changes include the transformation of the log's solid structure into ash and smoke as it combusts. The log changes color, often turning from brown or gray to black as it chars. Heat is produced, and gases like carbon dioxide and water vapor are released into the atmosphere. Additionally, the size of the log decreases as it loses mass through the combustion process.
Why people do not sink in saline water?
I think it is hard to swim under water in salt water because all of the salt is burning your eyes. It's just like being in a pool with too much chlorine in it. Thanks to the Holiday Inn I can't see good.
Can a log float above a water surface?
Yes, a log can float on water if its density is less than that of water. Logs are typically buoyant because they have a lower density than water, allowing them to float on the surface.
Logs sometimes float vertically in a lake because one end has become water-logged and denser than the other. What is the average density of a uniform-diameter log that floats with 54.0 of its length a?
To find the average density of a uniform-diameter log floating with 54.0% of its length submerged, we can use Archimedes' principle. The density of the log must be equal to the density of the water multiplied by the fraction of the log that is submerged. Assuming the density of water is approximately 1,000 kg/m³, the average density of the log can be calculated as follows: [ \text{Density of log} = \text{Density of water} \times \text{Fraction submerged} = 1000 , \text{kg/m}^3 \times 0.54 \approx 540 , \text{kg/m}^3. ] Thus, the average density of the log is about 540 kg/m³.
What are the properties of floating log of wood transported by water?
From the information you've provided ... that the log floats in water and is being transported by it ... the only properties that can be inferred are: -- The density of the log, in its aggregate entirety, is less than that of the water. -- The vertical dimension of the portion of the log below the water's surface is less than the depth of the water.
Why does a log of wood sink in water?
A log of wood sinks in water because wood is more dense than water. The density of an object determines whether it sinks or floats in a liquid. Since the density of wood is greater than that of water, the log sinks.
What is the density of Log Cabin Orignial Syrup?
The density of Log Cabin Original Syrup is approximately 1.3 grams per milliliter (g/mL). This indicates that it is denser than water, which has a density of about 1.0 g/mL. The syrup's density can vary slightly based on its formulation and temperature.
Is there gravity under water?
Definitely. A rock sinks in the ocean because gravity operates on it even under water. A log floats in water not because gravity stops under water but because the log's density is lower than that of the water.
Why does a log float?
An object will float on water if it has less density than the water. Or than any other liquid on which it is supposed to float.
Why does a large log of wood float on water but a steel needle sinks?
A large log of wood floats on water because its density is less than that of water, allowing it to displace enough water to overcome gravity and float. In contrast, a steel needle sinks because its density is greater than that of water, causing it to displace less water than its own weight and sink.
How can I protect my Myspace account from being hacked?
dont click on spams that will "log you off" to make u "log" back on. if that happends just exit the window && open a new one && log back on.
If A log is burning in a fireplace. If the amount of oxygen reaching the log is decreased what happened to the reaction rate?
If the amount of oxygen reaching the burning log is decreased, the reaction rate of combustion will also decrease. Oxygen is a crucial reactant in the combustion process, and insufficient oxygen limits the ability of the log to sustain a vigorous fire. As a result, the flames may become smaller, and the log will burn less efficiently. Eventually, if oxygen levels are too low, the fire may extinguish.
How do you use a pitometer log?
A pitometer log is used to measure a vessel's speed through water by comparing the pressure difference between water entering the log's inlet and the surrounding water. The device is typically mounted on the hull and works by measuring the dynamic pressure as the vessel moves. To use it, you need to read the displayed speed on the instrument, which can be calibrated to account for factors like water density and temperature. Regular maintenance and calibration are essential for accurate readings.
Can you tell why large log of wood floats on water but steel needle sinks?
Actually, the steel needle can float on water as well, so long as the surface tension is not broken. Answering the question, the buoyancy (ratio of density to that of displaced water) causes the log to float.
